IMPROVEMENT IN CULTIVATORS.

Specification forming part of Letters Patent No. 132,201, dated October15, 1872.

To all whom it may concern:

Be it known that I, BOWMAN S. 00X, of Paulsborough, in the county ofGloucester and State of New Jersey, have invented certain new and usefulImprovements in Cultivators,

. supports the cultivator-handles, and the slotted rack-bar, ashereinafter described.

In the accompanying drawing, A represents the central longitudinal beamof my improved cultivator. The forward part of this beam is bent to theform of an inverted U at a. B is a bent tooth secured to the beam, asshown. 0 represents oblique beams hinged at their forward ends to thebeam A. At their rear ends said beams are bent down and hold shovels d.The center beam is similarly bent down and also holds a shovel, d. Edesignates vinefenders attached to the lower part of the tooth B, thenceextending back on either side of the cultivator to some distance beyondthe beams O, and then bent around and back and secured'to the beams, asshown. These fenders should be pivoted or hinged to the tooth and to thebeams. Their object is to cast aside vines and trailing plants raised bythe tooth, and prevented from falling forward by the front leg of theU-bend on the beam A. The beam A is flanged or provided with'aprojecting plate at a. E is a cross-bar adapted to slide along saidplate, and provided with bent lugs e to serve as guides at the edges ofthe plate. This plateis connected to the oblique beams by means oftoggle-arms e. To the bolts securing these arms to the beams the rearends of the fender-rods are attached. To the bar E is pivoted an uprightlever, F, which has its fulcrum at the end of a standard, F, which is ofthe form of an inverted L, and is welded to or otherwise made to form apart of the beam A, thereby forming a substantial and convenient, aswell as comparatively inexpensive, support to the lever. To the rear endof the beam A is secured a frame, B, formed by bending a flat bar ofiron to a triangular shape and bolting or notchin g its ends to thesides of the beam. G indicates the cultivator-handles secured at theirforward ends to the cultivatorframe. Near their rear ends said handlesare rigidly secured to the inclined arms of the triangular frame B. Tothe middle part of the horizontal section of this frame is secured aslotted bar, I), having notches c. This bar extends forward and thelever F passes through the slot 0 A spring, 0 attached to one side ofsaid lever, serves to force and hold the lever into said notches. Bymoving the lever the beams O are adjusted to their desired positions.

Having fully described my invention, I claim- The cultivator having thecentral beam A holding the plate a, transverse bar E, and standard F theoblique beams O hinged at their forward ends to the beam A, andconnected to the bar E by pivoted arms 0; the adjustable fenders Epivoted to the tooth B and connected at their rear -ends to the beams O,and the operative devices for adjusting the beams and fenders, allsubstantially as and for the purpose specified.

In testimony that I claim the above I have hereunto subscribed my namein the presence of two witnesses.
